Searching for Immortality: Mortal Bones Against the Sky

Protagonist: Lin Yuan - born in a mortal village, born with mortal bones (unable to sense aura), accidentally saved a dying cultivator, and received the incomplete jade slip "Reverse Pulse Jue" as a gift. This technique can reverse the meridians and refine mortal bones into a true spiritual body, but the practice requires enduring the pain of tearing meridians, and each level of breakthrough requires devouring heavenly materials and earthly treasures. Nine Realms Immortal Continent: It is divided into nine regions, including Eastern Wilderness, Northern Ming, and Western Regions. Each region has top-level sects controlling resources. There is a "void rift" between the domains, hiding ancient secrets and evil spirits. Power disputes: The righteous way, the demon sect, and the ancient demon clan are divided into three parties, with undercurrents surging. It is rumored that the appearance of "Fragments of the Immortal World" will trigger major changes unseen in thousands of years. Ninth level of counter-vein (exclusive to the protagonist): Each level corresponds to a different phenomenon, such as the first level of "Bloodline Burning Flame", which can temporarily burn blood to increase combat power. The traditional immortal order: Refining Qi → Building Foundation → Golden Elixir → Nascent Soul → Transformation into God → Overcoming Tribulation → True Immortal. However, when the protagonist breaks through the "Reverse Pulse Jue", he is accompanied by a strange thunder calamity, which makes people fearful.
